Does not work.

I got this app in the beginning of my pregnancy with high hopes of fetal monitoring at home. Im now 37 weeks pregnant and with weekly attempts to hear heart tones, Ive gotten nothing. Ive followed the directions to a "t". I should also mention that Im a labor and delivery nurse with quite extensive experience finding fetal heart tones even in early first trimester. I have it two stars because the thought is nice I guess.
